Manganese-oxidizing Priestia sp. Z-MLHA-1 drives biogenic Fe-Mn mineralization for synergistic As(V)/Cd(II) co-immobilization in groundwater: Experimental and DFT mechanisms with sustainability implications.
Arsenic (As) and cadmium (Cd) frequently co-occur in contaminated groundwater, yet their distinct geochemical behaviors make simultaneous immobilization challenging. Here, a newly isolated Mn-oxidizing bacterium, Priestia sp. Z-MLHA-1, drives the formation of biogenic Fe-Mn minerals (BFMMs) through microbial Mn(II) oxi...
